Some parts are almost unwatchable...
I'm not sure what to think when Zizek comes as off as one of the more sensible thinkers groups. At least he, Appiah and Singer had a decent connection between their topics and their environs.
Most of the other philosophers strained to connect meaning to their setting. Hardt's lost on a dingy in Central Park. That guy is totally full of *beep* clueless to the extreme. He talks about transforming something he does not understand: human nature.
Nussbaum faithfully recites her schtick, motoring along at a pace one does not typically associate with the peripatetic philosopher.
By far the worst interview subject was the chick in the kimono. Wow. She has quite a racket goin' on.
Cornel West was typically all over the place, although I suppose apologists would say this jives with his jazz sensibility. He's the first speaker, I think he also appears somewhere in the middle, and again at the end. Thankfully he makes more sense as he goes along, and one of our final images is a pretty blond recognizing him on the street. Ah, it's good to be a public intellectual.
